This paper aims as the stability and large-time behavior of 3D incompressible Magnetohydrodynamic (MHD) equations with fractional horizontal dissipation and magnetic diffusion. By using the energy methods , we obtain that if the initial data is small enough in H3 (R3), then this system possesses a global solution, and whose horizontal derivatives decay at least at the rate of (1 + t) − 1/2 . Moreover, if we control the initial data further small in H3(R3) ∩ Hh −1 (R3), the sharp decay of this solution and its first-order derivatives are established.

This paper aims as the stability and large-time behavior of 3D incompressible Magnetohydrodynamic (MHD) equations with fractional horizontal dissipation and magnetic diffusion. By using the energy methods, we obtain that if the initial data is small enough in H 3 (R 3 ), then this system possesses a global solution, and whose horizontal derivatives decay at least at the rate of (1 + t) − 1 2 . Moreover, if we control the initial data further small in H 3 (R 3 ) ∩ H −1 h (R 3 ), the sharp decay of this solution and its first-order derivatives are established.
